Abstract
This utility model relates to petroleum-gas fiedl oil recovery, gas equipment manufacturing, innovative design is carried out for wellhead sealing and safety protective mechanisms, the hydraulic oil viscosity under higher than its operating temperature ratings driving piston in solving to make hydraulic flashboard blowout preventer because of gas production high temperature declines, and produces leakage and blood pressure lowering even a difficult problem for decompression.In blowout preventer body, design the circulating water cooling system that a low water level is entered, high water level goes out, reduce blowout preventer body temperature with recirculated water.Its advantage is delicate structure, compact, and endothermic effect is good, and cooling water can be recycled, and cooling water flow conduits is easy to safeguard.Can guarantee that hydraulic oil normally works under specified operating temperature, and the top extending flashboard assembly seals and front packing unit and the service life of preventer rubber seal everywhere.It is active in one's movements when closing preventer, closes reliable, eliminate the accident potential brought because of high temperature.
Description
Technical field
This utility model relates to the wellhead sealing during petroleum-gas fiedl oil recovery, gas and security fields, is specifically related in one
Put the hydraulic flashboard blowout preventer of recirculated water cooling.
Background technology
In gas production operation process, hydraulic flashboard blowout preventer is normally open.Flowline is had to lead in body Vertical Channel
Crossing, half envelope, full envelope and the shear ram assembly of the built-in many secondary difference in functionalitys of hydraulic flashboard blowout preventer, when needs flashboard assembly closes
Time, must be moved to channel center by preventer both sides piston simultaneously, during piston movement, rely on the hydraulic oil with proper viscosity to carry
For power.Present situation be stratum high-temperature reach the hot gases of 300 DEG C by flowline by hydraulic flashboard blowout preventer time, can pass to
Preventer amount of heat, makes preventer be in the condition of high temperature, drives the hydraulic oil of piston due to beyond nominal operation in preventer
Temperature and viscosity decline, the thinning hydraulic oil of high temperature not only can seepage, and decompression can be produced.So once stratum high pressure produces
Well kick and gas blowout accident and when requiring to close hydraulic flashboard blowout preventer immediately, piston action can be made slow even because of seepage or decompression
Malfunctioning, it is impossible to effectively driving flashboard assembly to make hydraulic flashboard blowout preventer lose efficacy to channel center's motion, whole production exists pole
Big potential safety hazard.Simultaneously high temperature also make flashboard assembly top seal and front packing unit and preventer rubber seal everywhere easy
In aging.
Summary of the invention
This utility model relates to the wellhead sealing during petroleum-gas fiedl oil recovery, gas and security fields, is that oil, gas well are in pass
Requisite transitional facility during well, the flashboard of adapted different size in order to seal variously-shaped and size drilling rod,
The instruments such as tool joint, drill collar, sleeve pipe, the most also can cut off flow string with shear ram, when in well without drilling tool, also can
The totally-enclosed well head of short-term.Hydraulic flashboard blowout preventer is aboveground operation and changes well head safe device important during downhole tool.
This utility model aims at and improves the above-mentioned deficiency of existing product and design, and its objective is to provide a kind of built-in recirculated water
Cooling system, mainly solution hydraulic flashboard blowout preventer is when gas production operation, because preventer high temperature makes hydraulic oil viscosity decline, thus anti-
The major safety risks that spray apparatus lost efficacy.Now change into the built-in circulating water cooling system of body, reduce complete machine temperature with recirculated water, make liquid
Force feed normally works under specified operating temperature.
The purpose of this utility model realizes with following technical scheme.Two sides before and after hydraulic flashboard blowout preventer body is divided
Not widening, and within it bore multiple uniform through hole, as cooling water channel, two ends, hole are provided with shrouding, enter with low level, and a high position goes out
Circulating water flow supercooling water channel, in order to fully absorb hydraulic flashboard blowout preventer body heat.This water cooling circulates in hydraulic flashboard
Also should normally use under preventer normally open, the most after a period of time, incrustation scale can be produced in cooling water channel and get rusty, removable
The shrouding design unloaded can conveniently carry out scale removal and rust cleans.
The beneficial effects of the utility model are delicate structure, compact, and endothermic effect is good, effectively reduces hydraulic flashboard blowout prevention
Device complete machine temperature, it is ensured that hydraulic oil normally works under operating temperature ratings, is active in one's movements, reliably when closing preventer, with
Time extend flashboard assembly top seal and front packing unit and the service life of preventer rubber seal everywhere, eliminate
The accident potential brought because of high temperature.

Detailed description of the invention
The purpose of the innovation realizes with following technical scheme.By two sides before and after hydraulic flashboard blowout preventer body 1 respectively
Widening, length is less than former body dimension, in boss-shaped, and within it bores the uniform through hole of even number, as S-shaped cooling water channel 2.,
A cooling water channel cover plate 9 is respectively designed in boss both sides, and cooling water channel cover plate 9 is connected by screw 11 and body 1 and is equipped with fluorubber
The cover plate for sealing pad 10 of material seals.Cooling water channel cover plate 9 structure of both sides is slightly distinguished, and side is cooling water channel transparent cover plate
901, side is cooling water channel boring cover plate 902, and a cooling water inlet is designed in cooling water channel transparent cover plate 901 bottom 1., upper design
One coolant outlet is 4..Cooling water inlet 1., cold go out water out be connected with inlet tube and outlet tube the most respectively (in figure end draw), and point
Do not join corresponding water valve coutroi velocity, it is achieved recirculated water low level enters, and a high position goes out, in order to fully absorb hydraulic flashboard blowout preventer body 1
Heat.It addition, because 2. S-shaped cooling water channel changes the position in hydraulic circuit hole in originally body 1, S-shaped cooling water channel 2. between
The hydraulic circuit of gap Position Design body 1 enters, spill port 3., the most matched hydraulic circuit hole on side door 3 is the most corresponding
Change.Furthermore, this cooling circulates in and also must normally use under hydraulic flashboard blowout preventer normally open, after a period of time, and S-shaped
